If you mean (1) y + 3x = 22 and (2) y + 2x = 16, then
(1) y = 22 - 3x (sub this into (2))
(2) (22 - 3x) + 2x = 16
-x = -6
x = 6
y = 22 - 3x = 22 -3(6) = 4
solution: (6,4)
Thanks to the browser, it is not possible to tell what the inequalities are.
Without a second independent equation, it's not a 'system' yet.
If you mean: y = x^2+4x+3 and y = 2x+6 Then the solution is: x = 1 or x = -3

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2). Neither y2x nor x 2y5 is an equation.
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
If you mean: y = x-2 and y = 2x-8 then it works out that x = 6 and y = 4

Without any equality signs the given expressions can't be considered to be equations so therefore there are no solutions.
y2x - just double the coordinate of y to get x. xy12 - i have no idea
If you mean: y = x^2+4x+3 and y = 2x+6 Then the solution is: x = 1 or x = -3

y2x is an expression, which cannot be graphed because we don't know what it equals. y = 2x, y2 = x, and 2y (or y2) = x are all things that could actually be graphed.
It is an expression in two variables, x and y.
